Defined in:
lib/locallingo/validators/duplicate_values.rb

Overview

Detects source-locale keys whose value matches an activerecord.attributes.* value. The AR key wins; the non-AR key is the "duplicate" and should reuse the AR key instead.

Operates on the flat source hash only, to avoid false positives from grammatical-form differences in non-English locales.

AR_ATTRIBUTES_PREFIX =
